The engines developed by Ford Racing are hungry engines, for both fuel and air. That's why Ford Racing has developed these upgraded throttle bodies. These throttle bodies from Ford Racing are high performance, heavy duty pieces of equipment designed specifically to increase engine output through increased input. Better airflow translates in to more horsepower and more torque. These high performance throttle bodies are available for Ford Mustang GTs and Boss 302s built from 2005 onward.
